WEATHER s'rRIP Application filed February 20, 1929. Serial N0. 341,502.

This invention relates to a weather strip particularly adaptable for use in connection with double sash windows and has for its primary ob] ect to provide, in a manner as hereinafter set forth, a means for sealing the air spaces between the upper sash and head of the window and between the lower sash and the window sill.

- A'further object of the invention'is to provide a weather strip as aforesaid, by means of a which air spaces at the top and bottom of the window may be efiectively closed, even though the sash is free-from contact with the sill or head, thereby compensatingfor any shrinking of the sash.

' A further object of the invention is to provide a weather strip as aforesaid, by means of which the lower portionof a window sash may be effectively protected from rain or the like, thereby eliminating the possibility of any swelling of the bottom portion of the sash due to saturation.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more particularly described, and as illustrated in the accompanying drawings wherein is shown a preferred embodiment of the invention, but it is to be understood that such drawings and description are to be taken as illustrative and that the invention is intended to be limited only by the scope of the claim hereunto appended.

In the accompanying drawings in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a sectional view of a weather Figure 3 is a transverse section of the weather strip showing the adaptation thereof with the lower sash and sill of a Window.

Figure 4 is an elevation of the'embodiment shown in Figure 3. V ,7 Figure 5 is a perspective view of the coacting sections of the strip, showing the same in disassembled relation. I I

Figure 6 is a sectional view of a modified form of my invention, showing the adaptation. thereof with window. 7

Referring to the drawings in detail, with particular reference to Figure 5, my improved weather strip consists of a pair of sec-i tions 1 and Qrespectively. The section 1 com prises an'innermember 3 of flat, elongated formation, and an outer member 4 which extends at an acute angle from one edge of the member 3 and the configuration of which is in,

the form of a compound curve. The section 2 comprises an anchor portion 5 which is semi-circular in cross section,-and a resilient grip portion 6 of ogee configuration, one

the upper and lower sashesof a' edge of which is connected to an edge ofthe.

portion 5 by means of a neck 7 The portion 6 extendsat an obtuse angle to the "anchor portion 5; The portion 5 is formed with a plurality of spaced openings 8 for the passage therethrough of suitable brads to secure the.

section 2 in position. The section l is formed with similar openings 9 at the bend between the portions 3 and 4 for the passage of brads or the like to secure the section 1 in position.

sash 10 and sill 11 0f a window, as illustrated in Figure 3, the section 1 is disposed with the free longitudinal edges 12 and 13 respectively of the portions 3 and 4 seating on the sill, with the inner portion 3 extend-W.

, To apply the sections land 2 to the lower...

into biting engagement with the upper face of the sill. The spaced relation of the edges 12 and 13and their biting engagement with the sill provides a double stop to prevent the passage of air or the likebetween the sill and the section 1. ThesectionQ is secured to the sash 10 bypassing brads 15 through. the Open- 2100 into contact,with-the portion 4,-the member material and the portion 6 of the section 2 is disposed at the proper inclination tohave an inherent tendency to swing inwardly.

Thus when the gripping member 6' is brought 6' will-he slightly sprung outwardly'tthereby drawingthe sash snugly against the portion 3 and insuring a close fitibetween'the mem-. -ber6 and-p0rtion 1 as soon as they are brought intooverlapping relation. 'lVhen the sash is moved in alongitudinal plane away from the sill,-a sliding contact is bad between theportions' 6 and 4,; and'owing to the ogee 5 surfaces are provided between such portionsv and compound curvatures of theportions 6- and 4 respectively, relatively wide bearing during such sliding contact;

As illustrated in Figured, the section 1 :is secured to the head 17' of the window int-he same manner as to the sill llexcept that the position of the section 1 is inverted withthe edges 12 and 13 thereof bearing against the lower-surface of thehead 117. The section .2 issecured to'the upper sill 18in the same;

manner as to the lower sashexcept that the :position of the section 2 is inverted.

. In the-modification illustrated in'Fig. 6,

'I employ-apair of sections19. andv 2O respec- .tively. The section 19consists' of;an anchor portion 21, a resilient gripportion 22, and a :fiat neck portion 28 connecting the. anchor and ,grip portions 21'and 22. The'anchor rected toward the lower face of the upper rail of thelower sash 10 and is driven in any suitable manner into biting contact therewith, preferably before the application of the holdfast devices 28. The resilient grip portion 22 has an inherent tendency to spring toward the depending portion 29 of-the section 20 whereby the portions22 and 29 may be effectively sealed to prevent the passage of air and the like therebetween as soon as such portions are brought into contact, even though the sashes 10 and 18 are not in their extreme closed positions.

It is. thought that the many advantages of a Weather strip in accordance with this in vention may be readily apparent, and although the preferred embodiments are "as illustrated and described, yet it'isto be understood that changes in the details of constructlon may be made, whichfall withinthe scope of the invention as definedin the rappended claim.

What I claim is: In-aweather strip for asliding sashtype of the window, and a'section for connection with the sash of'thewindow andhavi-ng a resilient portion extending at an angle. from the sash and snugly engaging. the outerface of the section connected with the-sill when the saslris closed, said resilient portion having an inherent tendency to spring inwardly'and :being forced outwardly when the sash-is closed wherebythe sashis drawn-snugly window, a section for connection withthesilli againstthe section connected with the sill? when the sash is closed and whereby-a sliding engagement is hadbetween the sections when the sash is moved in a'longitudinal plane away from thesill.

In testimony whereof, I aflix my. signature hereto.

portion 21 is semi-circular incrossrsection and suitably 1 apertured :for the passage of holdfast devicesr24. for securing the: section to-thelower face of the upper sash '18 of a window. With the holdfast'devices 24in place,-the neck portion 23 :pressed flatly against the sash 18 and the-free edge 25 of theanchOr portion 21 is drawn intobiting engagement therewith. The grip portion 22 is-of curved formation and extendsatx-an. in-
